Specification of Letters Patent.

Patented Apr. '11, acre.

Application filed January 11, 1916. Serial No. 71,548.

To all whom it may concern:

Be it known that I, WILLIAM M. CALD- WELL, a citizen of the United States, residing at El Reno, in the county of Canadian and State of Oklahoma, have invented a new and useful Hydrocarbon-Burner, of which the following is a specification. I

The present invention appertains to hydrocarbon burners, and aims to provide a novel and improved burner for consuming oil or other liquid fuel, the burner having a generator or retort for vaporizing the liquid fuel, and the vapor being discharged to support the flames for heating the generator or retort.

It is the object of the invention to provide a hydrocarbon burner which can be used in a stove, furnace, or elsewhere, for heating purposes, the burner being composed chiefly of piping, and havingvnovel means for supporting it in position upon the grate or other support.

The invention also includes means for controlling the outlet of vapor.

It is also within the scope of the invention to provide a hydrocarbon burner having the features above noted, and which is exceedingly simple and inexpensive 1n construction, as well as being practical and eflicient in use.

With the foregoing and other objects in view which will appear as the description proceeds,the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is an elevatlon of the burner. Fig. 2 is a vertical section thereof taken on the line 2-2 of Fig.1.

In carrying out the invention, there is provided a horizontal liquid fuel supply pipe 1, having its dlscharge terminal or portion 2 bent back downwardly to provide a U-shaped generator or retort 3, into which the liquid-fuel flows, the limbs of the retort 3 being arranged horizontally parallel with one another and in a vertical plane.

lower pipe 4 is-disposed in said vertical plane below and'parallel with the limbs of the retort 3, and is composed of two sections,

connected by a valve casing 5 in which a suitable valve 6 is disposed. Elbows 7 are attached to'the adjacent ends of the portion 2 and pipe 4, and said elbows are connected by a short vertical pipe section 8, whereby the vapor pipe 4 is connected with the-portron 2 of the retort. The other end-of the pipe 4 is closed by a screw cap 9, and each section of the pipe 4 is provided with an upper longitudinal series of outlet apertures or orifices l0 directed upwardly toward the portion 2 of the retort.

s a means for supporting the burner, a pair of transverse tubular feet 11 are employed, each of said feet having diametrically opposite apertures 12 through which the respective section of the pipe 4 is passed snugly. The feet 11 are arranged atthe opposite ends of the pipe 4, and said feet 11 are of larger diameter than the pipe 4, whereby the-b0ttom portions of the feet 11 seat upon the grate or other support, to hold the pipe 4 spaced thereabove. Set screws 13 are threadedthrough the tops of the feet 11 and bear upon the sections of the pipe 4, for clamping thefeet 11 in their adjusted positions, it being noted that when the set screws, 13 are loosened, the feet 11 may be adjusted longitudinally as well as angularly. The feet 11 can therefore be adjusted for properly supporting the pipe 4 with the retort properly above said pipe 4.

' When the burner is in operation, the liquid fuel Within is therefore vaporized, and the vapor will flow downwardly into the pipe 4 and thence out through the apertures 10 to support the The said flames will continue to retort to continually generate the heat the vapor, as long as into the retort. By closing the valve 6, the vapor cannot pass said valve, and will therefore only flow through those apertures 10 between the valve casing 5 and respective elbow 7, whereby the heating-effect is reduced, and when the valve 6 is opened, the heating effect is doubled or increased accordingly, since the vapor can flow into'the pipe 4 beyond the valve, whereby the vapor flows out all of the apertures 10.

the retort is heated, and

the liquid fuel is admitted Having thus described the invention, what a is claimed as new is: V

A hydrocarbon burner comprising a re tort, a pipe parallel therewith and having one end connected to one end thereof, said pipe having apertures directed toward the retort, a pair of transverse tubular feet of as my own, I have hereto affixed my signw larger diameter than said pipe and 1having ture in the presence of two Witnesses. diametrically opposite apertures, t rough 1 which said pipe extends, and set screws YWILLIAM CALDWLLL' 5 threaded through the tops of said feet and \Vitnesses;

bearing upon said pipe. OSCAR R. HOWARD, In testimony, that I claim the foregoing THos. G. JACKSON.
